TENS & NMES Replacement Batteries: Compatibility by Device
by Service, Training and SupportOctober 4, 2026
The right replacement battery for a TENS or NMES unit depends on its exact model, required voltage, and permitted battery chemistry. Some stimulators use a single rectangular 9V battery. Others take two or four AAs, use a rechargeable lithium pack, or require a dedicated clinical power supply. A battery that fits the compartment is not necessarily an approved replacement.
